Abstract

The invention relates to a dastarcus helophoroides larva feeding method and device. The device comprises a plastic feeding box, a plastic feeding box cover, square paper backing sheets and vertical-folding pupa wrapping paper. The plastic feeding box is 16-20cm in length, 9-12cm in width and 5-7cm in height, an opening of the plastic feeding box is provided with the plastic feeding box cover fittingly, and the square paper backing sheets and the pupa wrapping paper are sequentially put in the plastic feeding box, or outer convex rings of the plastic feeding box are arranged on the lower section of the periphery of the plastic feeding box. After the plastic feeding box and the matched plastic feeding box cover are disinfected, more than two layers of the square paper backing sheets are putat the bottom of the plastic feeding box, tenebrio molitor pupae wrapped by the vertical-folding pupa wrapping paper are uniformly put on the square paper backing sheets, and then the plastic feedingbox is covered with the plastic feeding box cover and put into an artificial climate box at the temperature of 28 DEG C and in humidity of 70% to realize culture. By replacement of test tubes with wood pulp paper, complex steps such as test tube cleaning and test tube disinfection are saved, and water absorption, ventilation, high moisture absorption efficiency, cleanness, convenience, effective space utilization of the feeding box and high larva survival rate are realized.

Description

technical field [0001] The invention relates to biological control technology, in particular to a breeding method of natural enemy insects, in particular to a method and device for raising velvet parasite larvae. Background technique [0002] The effect of chemical control on the control of beetle borer pests is not satisfactory. Under the background that people pay more and more attention to the protection of ecological environment, biological control will be widely used. Dastarcus helophoroides is an insect belonging to the family Coleoptera. It has a high parasitic rate on longhorn beetle pests and strong environmental adaptability. In the process of biological control of longhorn beetles such as longhorn beetle, pine brown beetle, cloud-spotted beetle, and chestnut beetle, good control effects have been achieved. Therefore, in areas where longhorn beetle pests occur seriously, it is necessary to produce and release a large number of beetles to prevent and control the ha...
